' GASOLENE-FILTER.

Specification of Letters Patent.

Patented Aug. 13, 1912.

Application filed March 6, 1912. Serial No. 681,901.

To all whom it may 0012 cam Be it known that I, FREDERICK ll. 5117mm,

1 a citizen of the United States, and a resident of the city of New York, borough of the Bronx, in the county and State of New York, have invented a new and Improved Gasolene-Filter, of which the following is a full, clear, and exact description.'

My invention relates to a new and improved'form of gasolene filter. and an object of my invention is to provide a device of the above indicated character "from which the water or other lvavy substance will be battled and precipitated from the gasolene before the latter passes through the screens common to devices of this character.

A further object of m invention is to provide a device from whic 1 the'screens may be readily removed and inserted,

A still further object of my invention is to provide a device of the above indicated character which may be readily cleaned and in which the several parts may be quickly assembled or removed.

Iattain the above outlined objects by con-- structing a two-part cylinder having an inlet at one end and an outlet at the opposite end. Depending from the side having" the inlet is a trap, disposed between which trap and the outlet isa battle screen having an opening at its upper end, through which opening the gasolene is allowed to pass on its way to suitably disposed screens, which screens are carried in a shell removably placed in the part of the cylinder between the baflie plate and the outlet.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures, and in which- Figure 1 is a vertical sectional view taken through a preferred embodiment of my device; Fig. 2 is a vertical transverse sectional view taken on the line 22 of Fig. 1, and looking in the direction of the arrow, and Fig. 3 is an elevation of the batlle plate.

Described more in detail, I have shown a cylinder 4, preferably constructed of two substantially equal parts, fastened together by means of a plurality of screws passing through abutting flanges 6 extending from the meeting edge of each half of the cylin- (18I';%1e portion of the cylinder, hereinafter re rre to as the inlet part 7 has a suitably constructed inlet connection leading thereinto. l,hreaded into a flanged opening 9 in the lower portion of the inlet part 7, is an externally screw-threaded sleeve 10, the lower end of which is engaged by a trap 11 in the form of an inverted dome, the lower end of which has an outlet 12 normally closed by a screw IS. The inlet part 7 has a grooved recess l-lin its flanged end, the shoulder 15 formed by said recess having a plurality of spacedapart indentations 16 therein. Resting on said shoulder l5 is a substantially segment-shaped ballle plate 17, having teeth 18 projecting therefrom and adapted to engage in the indentations 16. to prevent said plate from rotating in its own plane. The upper straight edge 1.) of the plate 17 terminates below the upper side of the bore of the cylinder l, so as to form an overflow opening 20 for the passage of the gasolene over the battle. it will be understood that the gasolenc comingthrough the inlet 8 is checked by the ballle plate, permitting water or other heavy liquid or substance to {low through the pipe 10 into the trap 11, and ])(.l'lllltlll1 the lighter gasolene to flow over the plate 17.

Disposed in rear oi the plate 17 and in the recess 14,, is the first screen 21. which screen and plate are held in position by the adjacent edge of the outlet port 22 of the cylindcr 4;. Hearing upon the screen 21 and extending into the outlet part 22, is a helical spring" 29 having an external diameter substantially equal to the diameter of the bore of the cylinder 4, said sprinp having the convolution 2-3 at the e.nd opposite the screen 21 oi smaller diameter and ad pted to lit within a shell 2i and to bear upon a ring 25 slidably mounted in said shell. The shell has positioned therein a plurality of removable screcns 26, which screens are held in position between the ring 25 and the peripheral flange 27 forming the outer end of the shell 24. Leading from the outlet part 22 of the cylinder t is an outlet 28 of any suitable construction,

It will be seen from the above outlined construction that the two portions of the cylinder 4t may be readily disconnected by tmtasteninnthe screws 5, thereby permitting the ejection of the spring 29 and the removal of the screen 21 and battle plate 17. at the same time, the shell 24 and its containing spring may be withdrawn from the Patent:

open end of the outlet portion 22 and the screens cleaned or new screens inserted in- 1. A gasolene filter comprising a cylinder having an inlet at one end and an outlet at the opposite end thereof, said cylinder formed of' two component parts, abutting flanges carried by said parts, one of said flanges having a recess in the abutting face.

thereof, a fluid-checking element disposed on the shoulder formed by said recess, said element being held in place by the end of the adjacentpart, a'screen disposed in said adjacent part, a coil spring having one end supported by said element and the opposite end acting on said screen, and a trap in fluid connection with said cylinder on the side of said element opposite said screen.

2. A gasolene filter comprising acylinder having an inlet at one end'and an outlet at the opposite end thereof, said cylinder formed of two'component parts, abutting flanges carried by said parts, one of said flanges having a recess therein, a fluidchecking element disposed within said recess, said element held in place by the end of the adjacent part, a screen disposed in said adjacent part, and a coil spring, having one end acting on said element and the opposite end on said screen, to maintain thescreen spaced from said element.

8, A gasolene filter comprising a cylinder having an inlet at one end and an outlet at the opposite end thereof, said cylinder formed of two component parts, abutting flanges carried by said parts, one of said flanges having a recess-therein, and a fluidchecking element disposed in. said recess, said member being held in place by the end of the adjacent part- 4. A gasolene filter comprising a cylinder having an inlet at one end and an outlet at the oppos te end thereof, a shell disposed within said cylinder, a screen carried by said shell, a ring within said shell and bearing on said screen to hold the same in posi tion, and a spring bearing on said ring to maintain" said ring in contact with said screen.

. 5. The herein described gasolene filter comprising, in combination, a cylinder having inlet and outlet openings, a vertical solid bafiie plate fixed in said cylinder between said openings, said plate being adapted to check the'flow of gasolene but permitting the same to flow thereover after being checked, a plurality of screens between the plate and the outlet opening, and a spring acting to maintain said screens in spaced relation, the force of the spring at one end being resisted by said plate.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
